Microformats are fully specced with a
comprehensive test suite
and are licensed as Public Domain allowing you to freely use them however you want.

Parsing Microformats

If you’re a developer working on an app or service,
you probably need JSON as your input format.
Don’t worry.
There are several Microformats parsers written in multiple programming languages.
A parser will take a URL or a glob of HTML, understand it,
then convert it to JSON for your use.

You can test your URL here (or HTML snippet on any of the parser sites).
